cultivated our minds--they have made us think, wonder, and admire, and I
trust caused us to adore and reverence the Creator of this vast
universe. They have taught us the knowledge and value of time, and have
also shown the value of what man has been enabled to work out for his
own benefit and that of the world at large.

The chemist deals with the various substances brought under his notice,
thereby acquiring a knowledge of their properties, enabling him to
produce results which are truly beneficial. This knowledge is power.

The painter makes the features of Nature his study, and by his brush
delineates them on the canvas, and thus by knowledge of art he exhibits
power.

The astronomer's science is one of vast magnitude and importance--the
study of it embracing both science and art: science in the various
intricate calculations he requires to make in connection with the
heavenly bodies. By his researches we have discovered the form of the
earth and other planets, their respective distances from each other,
their revolutions, their eclipses and their orbits, and, more wonderful
still, the precise time when the various movements of each occur. In
art, the astronomer has originated and perfected the many powerful and
beautiful instruments now required for taking observations, and these,
when compared with the instruments in use in bypast times, are excellent
evidences of modern progress in this direction. Our wonder is excited
when we look at the instruments formerly in use; that so much was done
through them, and the advance made by art in the perfection of those now
adopted, show us again that knowledge is power.

The navigator, by a combination of astronomy and seamanship, is enabled
